Abstract

Arrayed-buoy wave energy converter is a system that converts wave energy into electric energy by arranging a plurality of energy conversion modules on a platform. It is possible to expand or reduce to various power generation capacities through the arrangement of proven conversion modules, and it is easy to maintain by separation by module. In order to arrange a plurality of power generation modules, the device is designed to be wide in the width direction so that more energy conversion modules are arranged, and therefore, analysis of the motion and structure safety of the platform is necessary due to its wide shape. In this paper, to design the platform shape of the legged type arrayed-buoy wave energy converter in which the rotor is arranged in the longitudinal direction, the change of the motion response characteristic is analyzed by the potential numerical analysis considering the size change and the rotor existence on the rectangular and circular platform sections, and then optimal platform shape is proposed.
